Diverter Controls

 

We custom design and manufacture Diverter Control Units according to your specifications and requirements,  The Diverter Control Unit is a free standing skid unit that provides an easy access point to function the Diverter.

Where applicable, the control system shall be capable of switching the diverted flow from one vent line to the other (e.g., port to starboard) while the diverter packer is closed without shutting in the well.

 

Key Features

Manipulator Valves provide a means to manually function the Diverter from a local panel, should communication were to be lost.

 

Gauges are used to visually monitor the system pressure and Needle Valves are used to isolate a circuit for servicing, push buttons control the pressure of the regulated circuits, and Block & Bleed Valves provide a safe means to perform maintenance on the system.

Operating the system is carried out at local Operator panel or the various HMI Panels (MCS, DCP, and TCP). The PDU provides the electrical supply, the HPU & RMU provide the hydraulic supply, and the pneumatic supply comes from rig supplied air.

 

Hydraulic Power Units

     

HMC Instrumentation & Controls offers a range of custom designed hydraulic power units ranging from small special purpose systems to large diesel engine powered hydraulic systems.

Wellhead Control Panels

     

 

Control systems are custom designed according to your specifications and requirements. These include HPU and/ or Control Modules for either single well or multiple wells. The wellhead panels are designed to control one SSSV & two SSVs. The sequence of closing shall be as per customers requirements. System monitoring devices provide the capability for automatic ESD upon abnormal condition and fusible loop fire protection. The HPU is self contained and integrated with the main panel for convenience and space savings. Accumulators, where required are provided for fluid storage in ESD applications..

Hydraulic pumps are powered by platform gas or air supply. The wellhead control consoles house the master control valve(s), sensors, ESD logic devices, flow-line pilots, manual reset relays, test manifolds, time delay circuitry and monitoring gauges. In case of panels for multi-well applications, each well module can be isolated or replaced without affecting other wells in operation. The control consoles are built from SS316 or SS316L materials for corrosive environments. The components can also be supplied in SS316 as required and available.
